citizen of the United States, residing at Los Angeles. in the county ofLos Angeles and useful Improvements in Car Couplers` of which thefollowing is a specification.

One object of my said invention is the provision in a car coupler ofautomatic type of simple and inexpensive means for assuring the couplerjaw assuming an open position when cars are moved apart, therebyassuring proper operation4 of the jaw and an ef-L fective coupling whencars come together and this in such manner as to obviate the necessityof a trainman going between cars in order to open or correctly positionfor coupling the jaw of the coupler.

Another object of the invention is the provision of improved means forthe purpose indicated in the form of an attachment readily applicable toautomatic couplers such as at present in general use.

To the attainment of the foregoing, the

invention consistsv in the improvement as hereinafter described anddefinitely claimed. In the accompanying drawings, forming part of thisspecificationz Figure 1 is a plan view showing as connected two couplersconstructed in accordance with my invention.

Figure 2 is a plan view of one coupler with the jaw in open position.

Figure 3 is a side elevation of the same.

Figure 4 is a side elevation of a coupler as it appears with the jaw inclosed position.

Figure 5 is a detail elevation showing the pin and spring comprised inmy improvement.

Figure 6 is a fragmentary inverted plan.

Similar numerals of reference designate corresponding' parts in all ofthe views of the drawings.

Figure 1 clearly illustrates that couplers constructed in accordancewith my invention are adapted to be connected together in the strong andsafe manner common to automatic couplers.

My novel couplers are identical in construction and therefore a detaileddescription of the coupler shown in Figures 2 to 6 will suffice toimpart a definite understanding of all. The coupler referred to includesa drawhead 1, a jaw 2, a pin 3 pivotally connecting the jaw 2 to thedrawhead, and a CAB. COUPLES.

spring 4 for assuring movement of the'jaw 2` to the open positionimmediately followingthe raisingof the locking pin 5 of the coupler, andthe drawing of two couplers apart. In the drawhead 1 is provided anopening 6, Figure 3, to receive the pin 3, and-at the underside of thedrawhead 1 and surrounding the said opening 6 is a boss Y, immediatelybelow which is a supplemental boss 8, Figures 3, 4 and 6, the saidsupplemental b oss 8 having radial grooves 9 which extend throughout itsdepth. Said supplemental boss 8 may be and preferably is inte-v gralwith the boss 7. The jaw 2 is of con ventional configuration and isprovided in one of its arms with an opening 10 to receive the pin 5, andin its other arm with an opening 11. The pin 3 is disposed in thedrawhead 1, and is locked against turning in the drawhead through themedium of a cotte:` pin 12, best shown in Figures 3 and 6, which cotterpin extends through a diametrical aperture in the pin 3, and is seatedin alined grooves 9 of the supplemental boss 8. The spring 4 is providedwith an arm 13 which extends through an aperture in the upper portion ofthe pin 3, and in virtue of the said cotter pin l2 in combination withthe grooved supplemental boss 8, the pin may be adjustably positionedand fixed so as to correctly tension the spring 4 as differentconditions require. In addition to the terminal arm 13 the spring 4includes convolutions 14, an arm 15 and a pendent loop 16 on said arm15, the said pendent loop 16 being designed to be socketed in the jawopening 1 1 as clearly shown in Figures 2 and 3. Manifestly when sosocketed the loop 16 will be compressed, see dotted lines in Figure 3,and hence it will tend to retain itself by frictional Contact in the jaw2.

It will be apparent from the foregoing lbe readily embraced in couplerssuch as at present in use. I

I have entered into a detailed description of the construction andrelative arrangement of the parts embraced inthe present andpreferredVembodiment of my invention in order to impart a full,` clear and exaot.understanding of the said embodiment. I

do not desire, however', to be understood vas confining myself to thespecific construction and relative arrangement of parts inasmuch as inthe future practice of the invention varionsV changes and modificationsmay be made such as fall AWithin the scope of 'my invention las definedin my appended Claim. Having described my invention, what I claim anddesi-re to secure by Letters'Patent, is n Incombination, a draw headformed with a vertical :pin receivingv opening, -a 'jaw member, a pivotpin extending through'an opening in the jaw member, and the pin receiviing opening of the dravv head -forp'ivotally Connecting the jaw memberthereto,- said draw headfbeing formed at 'one side with a plurality offslots adjacent the pin receivf ing opening and extending. radial-lyYtherefrom:j a Cotter pin extending. through the transverse opening inthe pivot andV surface of the draw head,V and the other end' of saidspring 'extending butward-ly 'from the coil and formed with 5alaterally" extend'-V ing terminal seatingin -an opening in the jawmember7 whereby the Cotter pin secures the pivot'pin against -a'xialmovement infthe draw head, looks'the diametriealendportion Y of thespringvin Ythe pin aga-instl the Lipper side ofthe draw head, V*and `isadaptedffor adjustment inthe radial slots 'to increase'or t decrease thetension ofthe spring for operatlngthe ]a\v"member tre.
